The deal is materially the same one the Obama Administration endorsed just a few months ago and was demanding that Iran agree to as recently as last month, but the US has condemned the deal, demanding Iran submit the offer formally for consideration by the IAEA, which they did today.

The current official line is that Iran “isn’t serious” about the deal because they have already attempted to enrich uranium to the levels needed to make the fuel rods themselves, though these efforts have been very limited and Iran has verbally pledged to abandon the 20% enrichment if and when an alternate source of fuel for its medical reactor, the source of isotopes for nuclear medicine for hundreds of thousands of Iranians, is found.
